Muslim conquest of the Iberian Peninsula in the context of "Christian reconquest"

Portugal, officially the Portuguese Republic, is a country on the Iberian Peninsula in Southwestern Europe. It is an unitary semi-presidential republic composed by continental Portugal and two autonomous regions, with Lisbon as both its capital and largest city. The continental portion borders Spain to the north and east, with Madeira and the Azores in the Atlantic Ocean. It features the westernmost point in continental Europe.

The western Iberian Peninsula has been continuously inhabited since prehistoric times, with the earliest signs of settlement dating to 5500 BC. Celtic and Iberian peoples arrived in the first millennium BC. The region came under Roman control in the second century BC. A succession of Germanic peoples and the Alans ruled from the fifth to eighth centuries AD. Muslims invaded mainland Portugal in the eighth century, but were gradually expelled by the Christian Reconquista, culminating with the capture of the Algarve between 1238 and 1249. Modern Portugal began taking shape during this period, initially as a county of the Christian Kingdom of León in 868, and formally as a sovereign kingdom with the Manifestis Probatum in 1179.

Sephardic Jews, also known as Sephardi Jews or Sephardim, and rarely as Iberian Peninsular Jews, are a Jewish diaspora population associated with the historic Jewish communities of the Iberian Peninsula (Spain and Portugal) and their descendants. The term "Sephardic" comes from Sepharad, the Hebrew word for Iberia. These communities flourished for centuries in Iberia until they were expelled in the late 15th century. Over time, "Sephardic" has also come to refer more broadly to Jews, particularly in the Middle East and North Africa, who adopted Sephardic religious customs and legal traditions, often due to the influence of exiles. In some cases, Ashkenazi Jews who settled in Sephardic communities and adopted their liturgy are also included under this term. Today, Sephardic Jews form a major component of the global Jewish population, with the largest population living in Israel.

The earliest documented Jewish presence in the Iberian Peninsula dates to the Roman period, beginning in the first centuries CE. After facing persecution under the Pagan and later Christian Visigothic Kingdom, Jewish communities flourished for centuries under Muslim rule in Al-Andalus following the Umayyad conquest (711–720s), a period often seen as a golden age. Their status declined under the radical Almoravid and Almohad dynasties and during the Christian Reconquista. In 1391, anti-Jewish riots in Castile and Aragon led to massacres and mass forced conversions. In 1492, the Alhambra Decree by the Catholic Monarchs expelled Jews from Spain, and in 1496, King Manuel I of Portugal issued a similar edict. These events led to migrations, forced conversions, and executions. Sephardic Jews dispersed widely: many found refuge in the Ottoman Empire, settling in cities such as Istanbul, Salonica, and İzmir; others relocated to North African centers like Fez, Algiers, and Tunis; Italian ports including Venice and Livorno; and parts of the Balkans, the Levant (notably Safed), and the Netherlands (notably Amsterdam). Smaller communities also emerged in France, England, and the Americas, where Sephardim often played key roles in commerce and diplomacy.

Córdoba (/ˈkɔːrdəbə/ KOR-də-bə; Spanish: [ˈkoɾðoβa] ), or sometimes Cordova (/ˈkɔːrdəvə/ KOR-də-və), is a city in Andalusia, Spain, and the capital of the province of Córdoba. With a population of 324,902 as of 2024, it is the 12th-largest city in Spain and the 3rd-largest in Andalusia.

The city primarily lies on the right bank of the Guadalquivir in the south of the Iberian Peninsula. Once a Roman colony, it was taken over by the Visigothic Kingdom in the sixth century and then conquered by the Muslims in the eighth century. Córdoba became the capital of the Emirate and then Caliphate of Córdoba, from which the Umayyad dynasty ruled al-Andalus. Under Umayyad rule, Córdoba was transformed into a centre of education and learning, and by the 10th century it had grown to be the second-largest city in Europe. The caliphate experienced a manifold political crisis in the early 11th century that brought about state collapse. Following the Christian conquest in 1236, Córdoba became part of the Crown of Castile as the head of the Kingdom of Córdoba.

The Reconquista (Spanish and Portuguese for 'reconquest') or the fall of al-Andalus was a series of military and cultural campaigns by Northern Christian polities against Muslim-ruled al-Andalus, which had previously been part of the Visigothic Kingdom before the Muslim Conquest of 711. The Reconquista concluded in 1492 with the capture of Granada by the Catholic Monarchs of Spain, thereby ending the presence of any Muslim rule on the Iberian Peninsula.

The beginning of the Reconquista is traditionally dated to the Battle of Covadonga (c. 718 or 722), approximately a decade after the Muslim conquest of the Iberian Peninsula began, in which the army of the Kingdom of Asturias achieved the first Christian victory over the forces of the Umayyad Caliphate since the beginning of the military invasion. By the early 11th century, the Caliphate of Córdoba endured state collapse into a series of petty successor states known as taifas. The northern kingdoms advanced further against these fiefdoms and often made them subject to a protection racket system.

The Iberian Crusades were papally promoted wars, part of the Reconquista, fought against the Muslim states of the Iberian Peninsula within the wider Crusading movement from 1095 to 1492. The Muslim conquest of the peninsula was completed in the early 8th century, when the Christian Visigothic Kingdom fell, yet the small realm of Asturias endured in the north-west. From the 9th century, its southward expansion against al-Andalus (Muslim Spain) was portrayed in local chronicles as a divinely sanctioned war of recovery. This expansion, along with Frankish advance, gave rise to new Christian realms—Navarre, León, Aragon, Castile, Portugal, and Barcelona—in the north. After al-Andalus split into taifas (small states) in 1031, the Christian realms exploited Muslim disunity to further expansion. From the 1060s, the papacy occasionally supported campaigns against al-Andalus by granting spiritual rewards to participants.

As the Reconquista advanced, the taifa rulers sought aid from the fundamentalist Almoravids of North Africa, who halted the Christian expansion. Soon after proclaiming the First Crusade for the liberation of the Holy Land at the Council of Clermont in 1095, Pope Urban II extended the same spiritual privilege—remission of sins—to Iberian lords who took up arms against the Moors (Iberian Muslims). Peter I of Aragon was the first ruler, in 1100, to fulfil his crusading vow within the peninsula, and his example was soon followed by others. Leading crusading armies, Alfonso I of Aragon captured Zaragoza (1118), Afonso I of Portugal seized Lisbon (1147), and Ramon Berenguer IV of Barcelona took Tortosa (1148). The renewed Christian advance provoked another North African intervention, this time by the Almohads, who could only temporarily halt the Christian expansion. Occasionally, the Moors' Christian allies, such as Alfonso IX of León were also targeted by crusading campaigns. After crusader forces inflicted a decisive defeat on the Almohads at the Battle of Las Navas de Tolosa in 1212, the Reconquista gained new momentum. Papal grants of crusade indulgence then supported James I of Aragon in the conquest of Mallorca (1231) and Valencia (1238), and Ferdinand III of Castile in the capture of Córdoba (1236) and Seville (1248), reducing al-Andalus to the Emirate of Granada by 1262.

In the sociology of religion, secondary conversion is the religious conversion of an individual that results from a relationship with another convert, rather than from any particular aspect of the new religion. For example, someone might join a religious group primarily because their spouse or partner has done so; such a person would be a secondary convert.

Secondary conversion can greatly expand a movement's influence, particularly after a conquest, such as the Muslim Moorish conquest of Spain and Catholic Spain's conquests in Latin America.
